Set of 6 Battery Water Level Indicator caps for monitoring and measuring electrolyte (acid or water) levels in automotive-style batteries that have removeable 1/4 turn bayonet style refill caps. Especially useful if you have a battery situated such that the view into its refill holes is blocked (e.g., Polaris Ranger electric UTVs, golf carts, etc.).
Set consists of:
- Qty 3 P/N 4000303 (1.25" Fill level) with adjustable red O-ring level indicator
- Qty 3 P/N 4000425 (1.39" Fill level) with graduated red-to-green scale level indicator & MIN / MAX markings
Though these handy gauges are designed for a specific depth of electrolyte, they are adjustable so that you can set or read the level over a wide range of depths.
Retail price from the manufacturer is $7.50 each + shipping.
